Abstract
Species composition and species richness were studied in lucidophyllous forests at their northern distributional limit in Akita Prefecture, Yamagata Pref., Niigata Pref., Iwate Pref. and Miyagi Pref., and at their upper distributional limit in Kagoshima Pref., Japan, in relation to environmental factors such as low temperature and salt breeze. In total, 79 stands in northern forest (26 on the Japan Sea side and 39 on the Pacific Ocean side), and 14 stands in upper forest (Kagoshima) were investigated. In two ordinations obtained by DCA using all occurring species, stands in northern forest and in upper forest were clearly differentiated. The northern and upper forests were differentiated by the occurrence of Cyrtomium falcatum, Persea thunbergii, Hedera rhombea, and 7 other species that were resistant to salt breeze and low temperature, and Quercus acuta, Neolitsea aciculata, Illicium religiosum and 13 other species that were non-resistant to salt breeze and resistant to lower temperature, respectively. In terms of life form spectrum, the northern and upper forests were characterized by the presence of evergreen herbs, and by the presence of lucidophyllous small trees and epiphytic ferns, respectively. The species richness (mean number of elements of lucidophyllous forest per 100m^2 stand) of forest at the northern limit, the upper limit and the distributional center (Aya, Miyazaki Pref.) were 7.0, 15.1 and 44.4, respectively. The species richness of the northern and upper forests was very low due to the low temperature. The lowest species richness at the northern limit appeared to result from environmental factors related to not only low temperature but also salt breeze.
